Now that I've found Autoslash, I won't be doing manual pricing anymore. I used to use a warehouse club discount, but they changed their website in a way that makes it much more difficult to compare prices and good deals are becoming rare. It's barely worth my time any more.
Enter Autoslash... I'm currently on a trip where they found a better deal for a fraction of the time. Tough to beat that!
For another upcoming trip, they found prices cheaper than the last couple of visits to the same city, and the latest pricing alert email result in moving up a vehicle class and SITLL paying less than the previous quote (for a lower class of vehicle).
Also, I had to email them with a question, and the response was quick and helpful. We even traded a few more emails about the company. Well done!!
